Yes, the lld macro has to be escaped. In this case you can try the workaround mentioned by Aleksandrs Saveljevs - adding space (or some other symbol) at the end of context:

{Template Virt VMware Guest:vmware.vm.vfs.fs.size[{$URL},{HOST.HOST},{#FSNAME},free].avg(180)}<{$LOW_SPACE_LIMIT:"{#FSNAME}$"}

and macro {$LOW_SPACE_LIMIT:"C:\$"}
